refactor: migrate run commands to use oclif/core v2

[k80bowman]

Work item

This command migrates the run commands (run, run:detached, and run:inside) to oclif/core v2 (they were previously using v1) and deletes the run-v5 package.

Notes

Migrating these commands to oclif/core v2 means that users will need to add additional flags that they wish to run inside their dynos after a double dash (--). So, for example, where a user could have previously run the command heroku run bash --norc -a APP_NAME, they will now need to run heroku run bash -a APP_NAME -- --norc with the additional commands both at the end of the command and after a double dash.

There was also a report that when this update was made previously a user was having the order of their additional commands reversed. This was apparently fixed by downgrading the command to use oclif/core v1. I was unable to reproduce this error in the oclif/core v2 version, but it is an issue that may come up.

Testing

• Prep
  • Checkout this branch and run yarn and yarn build
  • Find/create an app with at least one dyno. In order to test run:inside you'll need to use an app that exists inside a private space.
• run
  • ./bin/run run bash --norc -a APP_NAME
    • You should get a message that says "Error: Nonexistent flag: --norc"
  • ./bin/run run bash -a APP_NAME -- --norc
    • Should open up a bash terminal.
  • ./bin/run run bash -a APP_NAME -- --norc --verbose
    • Should get a message that says "Running bash --norc --verbose on..." with the additional flags in the correct order
    • Should open a bash terminal
• run:detached
  • ./bin/run run:detached ls -a APP_NAME
  • You should get a message that ls is running on your app with a logs command to view the output
• run:inside
  • This feature only works inside of a private space for now. I created an app using the node-js-getting-started project in my own test space. I then had to use sudo to enable dyno-run-inside.
  • ./bin/run run:inside -a APP_NAME web.1 bash
    • A bash prompt should open in your terminal.
